[Monitoring of treatment for metastatic castration-resistant prostate cancer].

Treatments currently available for metastatic castration-resistant prostate cancer (mCRPC) include abiraterone acetate, enzalutamide, docetaxel, cabazitaxel, and radium-223. However, the optimal sequence of these agents is still unclear, and markers to predict treatment response and facilitate patient selection remain an unmet need. In terms of overall survival, it is crucial that patients receive all treatment options currently available. This requires early detection of progression as an indication for a treatment switch. In this context, a structured monitoring of treatment is important in clinical practice.
